Abstract

PURPOSE:To realize the favorable air circulation and at the same time obtain conditioned air with proper temperature from respective blow-off ports by a structure wherein the blow-off ports are provided in four directions on a decorative panel. CONSTITUTION:Indoor air is sucked by the rotation of a Sirocco fan driven by a motor 9 through a suction port 6 and an orifice 14 into the fan 8 and discharged to blowing-off openings A and B after being guided by scroll parts 13b and 13b' and 13c and 13c'. The air reached the blowing-off openings A and B are respectively divided by auxiliary scroll parts 13d and 13d' so as to be respectively blown against the long side parts 10a and 11a and short side parts 10b and 11b of respective heat exchangers 10 and 11 in order to be blown off into a room through air ducts 12a-12d from discharge ports 7a-7d. Accordingly, because conditioned air is blown off from the discharge ports arranged in four directions, uniform air conditioning is performed, even if a main body 1 is located at the center of the room. In addition, at this time, conditioned air, which is cooled or heated by passing through either one of the long side ports 10a, 11a or of short side ports 10b and 11b of the heat exchangers 10 and 11, is blown off through the respective blow-off ports 7a-7d.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an air conditioner installed buried in the ceiling of an air-conditioned room.

Conventional Structure and Problems Conventionally, this type of ceiling-embedded air conditioner (hereinafter referred to as an air conditioner) has generally been shown in FIGS. 1 and 2. That is, in this figure, a indicates the main body of the air conditioner which is buried in the ceiling, and b indicates a decorative panel which is exposed from the ceiling to the outside and installed on the main body.

A blower C is installed approximately in the center of the air conditioner main body a, and the indoor air passes through the inlet d of the decorative panel b, exits the blower C, passes through the left and right heat exchangers e, passes through the air path f, and then enters the inlet 8. It is discharged indoors from the discharge ports 9 on both sides.

Another feature of the ceiling-mounted air conditioner is that it is installed almost in the center of the ceiling of the room, but the air discharged from the outlet q is in two directions, so the circulation of the conditioned air is poor and the air conditioner does not reach every corner of the room. It had some serious drawbacks.

This is an even more serious drawback in commercial air conditioners, where the room being air-conditioned is large and the air conditioner itself is large.

Purpose of the Invention Therefore, in order to solve the above-mentioned drawbacks, the present invention improves air circulation by providing discharge ports in four directions of the decorative panel, and provides comfortable air conditioning by obtaining conditioned air at an appropriate temperature from each discharge port. The purpose is to obtain something that can do the following.

DESCRIPTION OF THE INVENTION In order to achieve this object, an abbreviated heat exchanger is placed symmetrically with respect to the blower, instead of the conventional linear arrangement of exchangers, and four directions are arranged on each side of the heat exchanger. A ventilation passage connected to the discharge port is provided to discharge cooled or heated conditioned air in each of four directions.

Description of examples An embodiment of the present invention will be described below with reference to the accompanying drawings.

In the figure, 1 is the ceiling-embedded air conditioner body, and 2 is the ceiling-mounted air conditioner.
A rectangular box body 4 with an opening on the bottom side is inserted through an opening 3 bored in the ceiling 2 and is located inside the ceiling 2, and a box body 4 is exposed from the ceiling 2.
It consists of a rectangular decorative panel 53L that is fixedly attached to.

A suction port 6 is formed in the center of the decorative panel 5, and four discharge ports are formed on the outer periphery of the suction port 6 by a pair of long discharge lowers a and 7b and a pair of short discharge lowers c and d. On the other hand, inside the box body 4, a single suction sirocco fan 8 and a motor 9 for driving the fan 8 are provided opposite to the suction port 6, and a pair of L-shaped heat exchangers are arranged around the outer periphery of the sirocco fan 8. 10.11 is placed.

This arrangement is symmetrical with respect to a center line that is perpendicular to the center of the fan 8. L-shaped heat exchanger 10.11
consists of long sides 10a, 11a and short sides 10b, 11b, and the long sides 10a, 11a are ventilation channels 12a, 12.
17 through b and a long discharge lower a.

7b, and the short sides 10b and 11b are ventilation passages 12C,
It communicates with the short discharge lowers c and 7d via 12d.

Ventilation by the sirocco fan 8 to the L-shaped heat exchanger 10.11 is guided by a drain pan scroll 13 integrally formed of a heat insulating material such as expanded polystyrene. That is, the drain pan scroll 13 includes a drain pan portion 13a that receives drain water from the heat exchanger 10.11, and a blowout opening A that surrounds the outer periphery of the sirocco fan 8 and faces the heat exchanger 10.11.
, Scroll parts 13b, 13b' and 13 that constitute B
c, 13c' and the long side 10 located within the openings A and B.
a, 11a and an auxiliary scroll portion 13d that guides the flow to the short side portions 10b, 11b.

13d'. Furthermore, a suction opening 13e is bored in the medium heat of this drain pan scroll 13, located on the suction side of the sirocco fan 8, and the suction opening 13e is provided with an orifice 14. In this configuration, indoor air is drawn into the suction port 6 by 80 rotations of the sirocco fan driven by the motor 9. It is sucked into the fan 8 through the orifice 14, and the scroll part 1
3b, 13b' and 13c, 13c', the blowing phase opens A, B-\ and is discharged. The flow is separated from the blow-off openings A and B by the auxiliary scroll parts 13d and 13d', and flows into the long sides 10a and 11a and the short side 10 of the heat exchanger 10.11.
b, 11b and is blown into the room from the discharge lowers a to 7d via the ventilation passages 12a to 12d.

Therefore, conditioned air is blown out from the discharge lowers a to 7d in four directions, and even if the main body 1 is located in the center of the room, air conditioning can be performed evenly. 10.11 long side 10a, 11a1 short side 1
Cooled or heated conditioned air is blown out through ob and 11b.

Effects of the Invention As is clear from the above explanation, according to the present invention, an abbreviated heat exchanger is arranged symmetrically surrounding the blower, and discharge ports of the decorative panel are arranged corresponding to each side of the heat exchanger. When discharging air in four directions, it is possible to discharge heat-exchanged conditioned air to each discharge port, and it also has the effect of uniformly conditioning the indoor air compared to conventional two-way discharge air conditioners. have Furthermore, using a pair of abbreviated heat exchangers, 4
Since it is a directional blowout, the arrangement is easy and it can be manufactured at low cost.
